strigazisapd: have you upgraded the database for queens? I don't see this problem in pike, queens or master09:18
sapdstrigazi: Yes, I did. I have to create a quota for this project before create cluster.09:19
strigazisapd: this exception is caught here: https://github.com/openstack/magnum/blob/stable/queens/magnum/api/controllers/v1/cluster.py#L41909:20
sapdstrigazi: I think this quota have to set default like nova or cinder.09:21
strigaziI don't understand why you get this error. Do you have a traceback?09:21
strigazisapd: it doesn't have to, if there are not quota you get the default09:21

strigaziFrom my side, I had to report back on upgrades, the trust rotation issue and test the dashboard with calico and flannel.10:04
strigaziI managed to work only on the dashboard last week and I have some findings:10:05
strigaziThe following input comes from our profuction deployment. We run queens since wednesday \o/10:06
slunkadnice!10:06
flwangcongrats!10:06
strigazi1. to access the dashboard using kubectl proxy over the api server we need flannel or calico to be running on the master node(s)10:07
*** sidx64 has quit IRC10:08
strigazirunning flannel is just one line to run it as a system container, since the config is already there. For calico, we will need kubelet back on the master, probably kube-proxy as well.10:08
strigazi2. heapster and ipv6 :)10:08
flwangstrigazi: sorry, do you mean with flannel? we still need a fix to make dashboard works?10:09
strigazito work with kubectl proxy, yes10:09
flwangand the fix is running flannel on master?10:10
strigaziyes10:10
flwangstrigazi: ok, thanks10:10
strigaziunfortunately, yes10:10
flwangstrigazi: does that mean the flannel+dashboard never worked before?10:11
flwangwith kube proxy10:11
strigaziflwang: not never10:11
*** sidx64 has joined #openstack-containers10:11
strigaziflwang: it used to work, one of the changes, f27 or 1.9.3 broke kubectl proxy10:12
*** salmankhan has joined #openstack-containers10:12
*** sidx64 has quit IRC10:13
flwangok10:13
strigaziI can track it down10:13
flwangstrigazi: ok, you know my fix for calico is there10:13
*** ykarel|afk is now known as ykarel10:14
strigazifyi, We had the dashboard with flannel working for at least two years10:15
flwangstrigazi: hah, that doesn't mater now ;0)10:15
*** mgoddard_ has joined #openstack-containers10:17
strigaziIt does, I'll push a fix upsteam10:17
*** sidx64 has joined #openstack-containers10:18
strigaziipv6+heapster, I found out, that kubernetes take the node ips from the cloud-provider10:18
*** sidx64 has quit IRC10:19
flwangwhen i say 'it doesn't matter', i mean 'at least two years' doesn't matter, because it's broken now and we need to fix it asap10:20
strigaziIn kubelet we use all interfaces of the node which you would expect to the ips from the node, however the ips are advertised to heapster from the cloud provider and the metadata server.10:21
strigaziAnd if you have ipv6 ips heapster will try to use those and likely it will fail.10:21
strigaziI don't know what is the impact of this to other clouds. Downstream we will set the ipv4 to kubelet.10:22
strigaziflwang: slunkad have you used kubernetes with ipv6?10:22
flwangstrigazi: no10:22
slunkadstrigazi: nope10:22
strigazinice10:23
strigaziThat's a good exercise that we will have to do at some point.10:23
strigaziThat's it from me, I'll carry my items for next week.10:24
slunkadif we have no use case atm for ipv6 can't we use ipv4 upstream too?10:24
*** sidx64 has joined #openstack-containers10:24
slunkadfor heapster by default I mean10:24
strigazislunkad: I think we should have more input on this10:25
slunkadsure10:25
strigazislunkad: last week you said you are intersted on trust rotation, do you have time to take it?10:26
slunkadstrigazi: yes I can10:26

strigaziflwang: you had to check cotyledon as a replacement and test calico. Any findings for the meeting?10:32
flwangstrigazi: no, sorry, i was working on the calico+proxy issue10:33
flwangi will check cotyledon this week10:33
strigaziflwang: do we need kube-proxy too in the master node?10:34
flwangstrigazi: no10:34

strigaziA kubernetes node always has a both services running10:37
flwangstrigazi: i will give it a double check10:37
*** mjura has joined #openstack-containers10:37
flwangbut i don't think we really need it if it's not necessary10:37
*** sidx64 has quit IRC10:38
flwangstrigazi: btw, i'm testing prometheus monitoring and ingress now10:38
strigaziCan you check when we might need it apart from the the calico+kubectl proxy use case?10:39
strigaziflwang: prometheus or heapster+influx+grafana?10:39
flwangprometheus10:39
strigaziflwang: We might want to move it in a different namespace from kube-system10:40
flwangyou mean when we need  kube-proxy on master?10:41
strigaziflwang: yes10:41
flwangnow is there any preference in the market between prometheus and heapster+influx+grafana?10:41
flwangstrigazi: no problem, will do the investigation10:41
strigaziflwang: prometheus can be used to monitor services and offer it in the cluster so users can leverage it and modify it.10:43
flwangbased on my understanding, we need kube-proxy on master only if there is pod on master need to be accessed by kube proxy10:43
*** sidx64 has joined #openstack-containers10:45
strigaziheapster+influx+grafana offers more static content for utilization metrics. Prometheus has more capabilities. AFAIK prometheus is prefered to store monitoring data for applications. heapster+influx+grafana is a proposed solution from the heapster team and it is coplimentary to kubernetes-dashboard10:45
